Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground buried sensor information wireless transmission apparatus and a system including the same,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for wirelessly transmitting an underground sensor information and a system thereof, and more particularly to a technology for wirelessly transmitting sensor information embedded in an underground to a gateway on the ground.

It is necessary to manage the earth pressure, settlement degree, water pressure, soil moisture condition and underground facilities (piping, electric wire, etc.) condition of underground environment in relation to the ground construction. Based data and so on.

In order to accomplish this, the sensor is buried in the underground and the measured data is received from the sensor. However, it is difficult to measure the buried environment and the facility status data using the existing embedded sensor in the ground because of the poor propagation environment. That is, since the communication environment in the underground has a large loss due to a metallic material with high conductivity and a lossy medium such as moisture, the radio communication distance between transmission nodes is very short.

Therefore, it is possible to provide information of sensors buried underground by using a radio transmission system using a magnetic field coupling capable of long distance communication. However, such a magnetic field system requires many burial operations such as a magnetic field coupling coil, There is a problem that it is not suitable for constituting a large scale communication network.
